About National Metal Fabricators

Our Motivated And Highly Skilled Team

Through our team of nine highly skilled design and manufacturing personnel, we are able to draw on huge industry knowledge, bringing experience and a craftsman’s attention to detail to class-leading technologies, to deliver outstanding results.

Warren Park

“As part of the National brand of companies we have the ability to service our customers requirements not only with engineering projects but also spring manufacture, wire & even pest traps. Our repairs & maintenance service offers customers NZ wide the option to repair damaged cages, barrows or any company asset rather than have to cover the cost to replace.

We are also the preferred supplier to the food industry for stillages & blast freezer racks & this is due to not only the updated design of both items but also the quality workmanship & reputation we have gained within the industry”

Calib Gurden

“I am relatively new to this role having only just started with NMF earlier this year. The first thing that impressed me was how quality & customer focused the team are on the floor & the wealth of knowledge they have collectively. We really are the “solution finders” & focused on delivering exactly what our customers require no matter how big or small the job is give me a call to find a solution that works for you.”

Calib Gurden

Operations Manager


“I have been with NMF for 3 months now & this is my first fulltime job since leaving school, so I really had no idea what to expect when starting. All the guys here not only made me feel welcome & part of the team, but they also take the time to explain & demonstrate different welding techniques to me making it easier to understand & learn.”

Hunter Dryden



“I have always wanted a career as a welder in the engineering industry but as I had no experience or work history, I found it difficult to secure employment. When I approached NMF they gave me the chance to demonstrate my welding ability & the very next day I was contacted & offered my dream job & I have never been happier.”

Josh Wilson



“I started with NMF in Jan 2024 & I assist with the assembly & final finishing process. NMF has given me the opportunity to learn & gain experience operating the many various machines used within the engineering industry & as I am in training  feedback on next steps on how to improve.”

Kynan Stansbury

General Duties


“I really like the team culture that we have here at NMF & the different projects that we get to fabricate & assemble. From wire structures like cages to the large steel blast freezer racks to even large H frames needed for irrigation hoses it’s great to gain experience working on these projects.”

Te Rata

“I have been with the company since early 2023. In that time I have learnt so much regarding welding & fabrication from the guys here who are some of the best welders in the industry.

We all take pride in the work we manufacture as we know the customer is receiving an item of the best quality & built by the best team of people.”

Cameron Pou

“I have been in the engineering industry most of my working career & not only do I get to pass on the knowledge & experience I have gained over that time to the younger guys, but I get to do it with the best tools, brand new welders & a fit to purpose workspace & workshop.”

Cameron Pou

Welder, Fabricator


“We are all one big team at NMF. From the Manager down to the guys on the floor everybody is focused on supplying the customer with a top-quality product, built to spec & on time.

We all take pride in being part of a team that has a positive culture & we all strive to be the best in the industry.”

Internationally benchmarked Design

Our product designers utilise Advanced Spring Design (ASD), which is a state-of-the-art drafting program developed in the USA by industry leaders Universal Technical Systems Inc. for the Spring Manufacturers Institute.

ASD allows accurate drafting and specification analysis of a wide range of products, including compression springs, extension springs, spiral forms, torsion springs, garter springs, snap rings, washers, beams, and torsion bars.

The critical criteria for a product are entered into the intelligent system, and the optimal design automatically configured, together with all specification details. This information is then passed through to one of our CNC machines for an absolutely accurate reproduction of the design.
